Log the set. It works out the next one.
Pick how today went and watch the target change. The numbers and the reasoning below come from the same progression rules your sessions use — run here on an illustrative bench press, not on anyone’s real log.

Most workout apps record what you did. Then leave the next session to guesswork.
- A logbook shows last week’s numbers. It doesn’t tell you whether to add weight today.
- Generic plans don’t notice when a lift stalls — so it stays stalled for months.
- Without weekly sets per muscle, weak points quietly stay weak.

Review and adjust
Records, trends and stalls are flagged from your history, with the reason for every change.
Built for anyone who wants to build muscle and strength with a plan that adapts to what they actually lift.
Double progression, per lift
Fixed weight, climb the reps, then add load — with load steps sized for each exercise, not one rule for everything.
Weekly volume per muscle
Hard sets per muscle group each week, so nothing is neglected and nothing is overcooked.
A coach that reads your log
Ask why a lift stalled; Coach Marcus answers from your logged sessions, not from a script.
Nutrition targets
Calorie and protein targets from your stats, adjusted from your bodyweight trend.

Questions
How does MuscleYou decide what I lift next?
Double progression from your own logged sets. Reach the top of the rep range on every working set and the load goes up by the right step for that lift; stall for three sessions and it suggests backing off instead.
Is it for beginners?
Yes. Tell it you are new and it keeps the exercise list simple, the volume moderate and the progression steps small.
Is the plan really free?
Building and viewing your plan is free and needs no account or card. Saving it and training with it needs Starter (a one-off payment) or Premium.
Do I need an account before seeing my plan?
No. Answer the questions, see your actual generated plan, then choose Starter or membership to save it and start training.
How does it know what weight I should lift?
From your own logged sets, not from a model guessing. It uses double progression: you work up within your rep range at a fixed weight, and once every working set reaches the top of that range, the weight goes up by the right step for that lift. If a lift has not moved for three sessions it says so and suggests backing off.
What do I get for €9.99?
Starter is a one-off €9.99 with no subscription: your 4-week plan and nutrition targets, guided workout mode with last session’s numbers filled in, the rest timer, automatic personal records and your full logbook. Premium works out what to lift next and why, charts trends, adapts your plan from your log, and adds the AI coach.
Is this medical advice?
No. Plans and targets are general fitness guidance. If you have a medical condition, an injury, are pregnant, or have a history of disordered eating, talk to a qualified professional before starting.
